# Sereact — AI foundation model that lets any robot adapt to new tasks.

Sereact builds Cortex, a vision-language-action foundation model that lets industrial and warehouse robots interpret natural-language instructions and handle tasks they were never explicitly programmed for, turning fixed machines into adaptable agents.

## Highlights

Notable milestones from Sereact’s journey — funding rounds, launches, and other moments worth knowing.

Launch - Apr 2026

### Cortex 2.0 lets robots simulate the future before they move

The second generation pairs the vision-language-action model with a world model: the robot generates candidate moves, runs them against a learned model of physics, and scores each for stability and risk before acting. By launch, Sereact had 200+ systems live across Europe past 1 billion production picks — roughly one in 53,000 needing a human.

**"One brain, any robot" — Cortex 2.0 running on both a humanoid and a fixed industrial arm.**

Funding - Apr 2026

### $110M Series B to scale the robotic brain and cross the Atlantic

Headline led the round — past $140M raised in total — funding the rollout of Cortex 2.0 and Sereact's first US office in Boston. Bullhound Capital, Daphni, and Felix Capital joined, with customers already including BMW, Daimler Truck, Mercedes-Benz, and PepsiCo.

### Cortex: one foundation model that thinks on its feet

Sereact unveiled Cortex, a vision-language-action model unifying perception, reasoning, and control so a robot can be redirected to a new task by instruction alone — no reprogramming — and generalise to objects it has never seen.

**Cortex driving a real pick — the model handles unfamiliar items without task-specific programming.**

### €25M Series A to take software-first robotics global

Creandum led the round, with Point Nine and Air Street returning and a roster of angels — F1 champion Nico Rosberg, ex-DeepMind's Mehdi Ghissassi, Helsing's founders, and Zalando's Rubin Ritter — backing Sereact's bet that any robot can be made adaptable in software.

### $5M seed for a "ChatGPT for robots"

Point Nine and Air Street Capital led the seed round behind Sereact's early transformer that let operators steer warehouse robots with plain language instead of code, joined by angels including a Cruise VP and the founders of Automata and Ascending Technologies.

### Two Stuttgart PhDs bet robots need a brain, not better hardware

Childhood friends Ralf Gulde and Marc Tuscher founded Sereact in Stuttgart after their doctorates at the university's robotics institute (ISW), wagering that software — not yet another arm — was the bottleneck keeping robots stuck on pre-programmed tasks.
